DESCRIPTION:
The IDT72401 and IDT72403 are asynchronous high-performance First-ln/First-Out memories organized 64 words by 4 bits. The IDT72402 and
IDT72404 are asynchronous high-performance First-ln/First-Out memories organized as 64 words by 5 bits. The IDT72403 and IDT72404 also have an Output Enable (OE) pin. The FlFOs accept 4-bit or 5-bit data at the data input (D0-D3, 4). The stored data stack up on a first-in/first-out basis. A Shift Out (SO) signal causes the data at the next to last word to be shifted to the output while all other data shifts down one location in the stack. The Input Ready (IR) signal acts like a flag to indicate when the input is ready for new data (IR = HIGH) or to signal when the FIFO is full (IR = LOW). The IR signal can also be used to cascade multiple devices together. The Output Ready (OR) signal is a flag to indicate that the output remains valid data (OR = HIGH) or to indicate that the FIFO is empty (OR = LOW). The OR can also be used to cascade multiple devices together. Width expansion is accomplished by logically ANDing the IR and OR signals to form composite signals. Depth expansion is accomplished by tying the data inputs of one device to the data outputs of the previous device. The IR pin of the receiving device is connected to the SO pin of the sending device and the OR pin of the sending device is connected to the Shift In (SI) pin of the receiving device. Reading and writing operations are completely asynchronous allowing the FIFO to be used as a buffer between two digital machines of widely varying operating frequencies. The 45MHz speed makes these FlFOs ideal for highspeed communication and controller applications. Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B.

NOTES: 1. Since the FIFO is a very high-speed device, care must be excercised in the design of the hardware and timing utilized within the design. Device grounding and decoupling are crucial to correct operation as the FIFO will respond to very small glitches due to long reflective lines, high capacitances and/or poor supply decoupling and grounding. A monolithic ceramic capacitor of 0.1F directly between VCC and GND with very short lead length is recommended. 2. This parameter applies to FIFOs communicating with each other in a cascaded mode. IDT FIFOs are guaranteed to cascade with other IDT FIFOs of like speed grades. 3. IDT72403 and IDT72404 only. 4. Guaranteed by design but not currently tested. 5. Military availability for IDT72403 is 10MHz, 35MHz, for IDT72404 is 15MHz, 35MHz. IDT72401 is available for all MHz.

SIGNAL DESCRIPTIONS INPUTS:
DATA INPUT (D0-3, 4) Data input lines. The IDT72401 and IDT72403 have a 4-bit data input. The IDT72402 and IDT72404 have a 5-bit data input.
INPUT READY (IR) When Input Ready is HIGH, the FIFO is ready for new input data to be written to it. When IR is LOW the FIFO is unavailable for new input data. IR is also used to cascade many FlFOs together, as shown in Figures 10 and 11. OUTPUT READY (OR) When Output Ready is HIGH, the output (Q0-3, 4) contains valid data. When OR is LOW, the FIFO is unavailable for new output data. OR is also used to cascade many FlFOs together, as shown in Figures 10 and 11. OUTPUT ENABLE (OE) (IDT72403 AND IDT72404 ONLY) Output enable is used to read FIFO data onto a bus. OE is active LOW.
CONTROLS:
SHIFT IN (SI) Shift In controls the input of the data into the FIFO. When SI is HIGH, data can be written to the FIFO via the D0-3, 4 lines. SHIFT OUT (SO) Shift Out controls the output of data of the FIFO. When SO is HIGH, data can be read from the FIFO via the Data Output (Q0-3, 4) lines. MASTER RESET (MR) Master Reset clears the FIFO of any data stored within. Upon power up, the FIFO should be cleared with a MR. MR is active LOW.

MILITARY AND COMMERCIAL TEMPERATURE RANGES
FUNCTIONAL DESCRIPTION
These 64 x 4 and 64 x 5 FIFOs are designed using a dual port RAM architecture as opposed to the traditional shift register approach. This FIFO architecture has a write pointer, a read pointer and control logic, which allow simultaneous read and write operations. The write pointer is incremented by the falling edge of the Shift In (Sl) control; the read pointer is incremented by the falling edge of the Shift Out (SO). The Input Ready (IR) signals when the FIFO has an available memory location; Output Ready (OR) signals when there is valid data on the output. Output Enable (OE) provides the capability of threestating the FIFO outputs. FIFO RESET The FIFO must be reset upon power up using the Master Reset (MR) signal. This causes the FlFO to enter an empty state, signified by Output Ready (OR) being LOW and Input Ready (IR) being HIGH. In this state, the data outputs (Q0-3, 4) will be LOW. DATA INPUT Data is shifted in on the LOW-to-HlGH transition of Shift In (Sl). This loads input data into the first word location of the FIFO and causes Input Ready (IR) to go LOW. On the HlGH-to-LOW transition of SI, the write pointer is moved to the next word position and IR goes HIGH, indicating the readiness to accept new data. If the FIFO is full, IR will remain LOW until a word of data is shifted out.
DATA OUTPUT Data is shifted out on the HlGH-to-LOW transition of Shift Out (SO). This causes the internal read pointer to be advanced to the next word location. If data is present, valid data will appear on the outputs and Output Ready (OR) will go HIGH. If data is not present, OR will stay LOW indicating the FIFO is empty. The last valid word read from the FIFO will remain at the FlFOs output when it is empty. When the FIFO is not empty, OR goes LOW on the LOW-to-HIGH transition of SO. Previous data remains on the output until the HIGH-to-LOW transition of SO). FALL THROUGH MODE The FIFO operates in a fall-through mode when data gets shifted into an empty FIFO. After a fall-through delay the data propagates to the output. When the data reaches the output, the Output Ready (OR) goes HIGH. Fall-through mode also occurs when the FIFO is completely full. When data is shifted out of the full FIFO, a location is available for new data. After a fall-through delay, the Input Ready (IR) goes HIGH. If Shift In (SI) is HIGH, the new data can be written to the FIFO. Since these FlFOs are based on an internal dual-port RAM architecture with separate read and write pointers, the fall-through time (tPT) is one cycle long. A word may be written into the FIFO on a clock cycle and can be accessed on the next clock cycle.

NOTES: 1. When the memory is empty, the last word will remain on the outputs until the MR is strobed or a new data word falls through to the output. However, OR will remain LOW, indicating data at the output is not valid. 2. When the output data changes as a result of a pulse on SO, the OR signal always goes LOW before there is any change in output data and stays LOW until the new data has appeared on the outputs. Anytime OR is HIGH, there is valid stable data on the outputs. 3. If SO is held HIGH while the memory is empty and a word is written into the input, that word will appear at the output after a fall-through time. OR will go HIGH for one internal cycle (at least tORL) and then go back LOW again. The stored word will remain on the outputs. If more words are written into the FIFO, they will line up behind the first word and will not appear on the outputs until SO has been brought LOW. 4. When the MR is brought LOW, the outputs are cleared to LOW, IR goes HIGH and OR goes LOW. If SI is HIGH when the MR goes HIGH, the data on the inputs will be written into the memory and IR will return to the LOW state until SI is brought LOW. If SI is LOW when the MR is ended, IR will go HIGH, but the data in the inputs will not enter the memory until SI goes HIGH. 5. FIFOs are expandable on depth and width. However, in forming wider words, two external gates are required to generate composite Input and OR flags. This is due to the variation of delays of the FIFOs.
